This course is an introduction to how to use relational databases in business analysis. You will learn how relational databases work, and how to use entity-relationship diagrams to display the structure of the data held within them. This knowledge will help you understand how data needs to be collected in business contexts, and help you identify features you want to consider if you are involved in implementing new data collection efforts. You will also learn how to execute the most useful query and table aggregation statements for business analysts, and practice using them with real databases. No more waiting 48 hours for someone else in the company to provide data to you – you will be able to get the data by yourself!

A very well designed course with no prior knowledge assumed. The discussion forums are very lively and queries (no pun intended) are responded to fairly quickly. A great option who wants to learn sql.
Its a very good class to learn to use SQL in a systematic manner, even if you had used SQL or are completely new. The two Databases ( Terradata and Dognition) gave a lot of valuable practice.
It was an Awesome course. Really enjoyed doing all the exercises. Now I feel quite confident to write any queries. Special Thanks to Professor Jana Schaich Borg for teaching so wonderfully!!!!!
I recommend this course although the exercise requires more time than the average courses in Coursera. If you complete it seriously on your own you will learn a lot in order to apply it at work.
